This invention. aims to provide novel means for mounting ahydraul-ic hozzle for f movement throughont 'a Wide range to previde .novel means for fre'gulatlng the ameunt of liquid Which ,flet vs through the nozzle.

It is Witlfin the proviile of the 'cliscloshr'e inve -tionherein disclosed, may be made Within the sedjpe effwhat i claimed, with:

out =c1epa'r tin'g from the spirit of the inyention.

In the accompanying drawings Fgure 1 'is a plan, wherein parts appear in herizo'ntal section; I

Figure 2 is a verticalseetio about 011 the line f Figure 1.

In carrying; euit Ithe IIVBhlJlOD, there provided a centralhollew body 1, having outwardly eite'ncle'l rachal arms 2,?th'epee' sages 3 of the arms? commtuiieating with theh'ody 1. Thearms 2 have eff-sets 4,1hte which extend thehpper "en'cls of 'outwarell closing 'valv'es 5 ac'l'aptecltc cooperate wvith seats 6 formed in the arms 2,]the upper ehcle of the valves '5 "being carriefl by Pi the off-sets 4, the valves 5, flies, being hingedly or pivotally mounted. iCouplmgs 8 are mounted "cletachahly, for mstan'ce by threading, on the outer ends of the? arms 2. The 'c0hplings8 are provideflwith depending sockets '9 in which feet 10 are helcl by securing -elerrren cs 11. When it 1s des red to mount-*theiartlcle (in a trive't, the feet 10 may be used; "or, if preferred, LEastemng "clevlc'es (not shovvn) may he extended downwardly through ears 12" which project outwardly from the periphery of the portable hotly 1.

There is a central Opening 14 in the top (if thebecly 1 and in the bettom the body 1 there is a ceritra'l Opening 115, the opening 15 beihg sb n lewhat smaller in diameter than 'the 'openi'ng 14. The' body 1 is su plied with,

aclepehding annular flange 16, located abe-u Vbs the o eningfle, and s pplied with an lar seat 17 in which is lbc'at'ecl an annular peeking 138;,the packingfbeihg eo straet d as desired. The bottomq of the body ,1 has a 15. n the lower surface ojftherilo r9 is ananhular reeessho,

The mimeral 21 marks a tubulari-ematle member or coupling. journaled-to tuif-h about a vertical axis Within the ppening '14,Withih the'packing 1'8 and within theepenirrg lfi. The member :21 has an eutstar'ltlihf flange 22 (and anti-friction devices, such *balls'2'3, are disposed between -the flange 22 the top of the body 1. The lower end of the tfihalar rotatabl'e memher 21 tapers, jas shown in Figure 2, and the member 1 suppliefl =a't itslower end with "a fbot'toin plate thickened rib 19 located about the p m-mg :60

The member '21 is equipped with lateral ports 31 which communicate with the interior of the lodcly'i l. Tl r'e rotatable memberrfll includes -an upstahcling' "extensionv 32 which may be rectahghl-ar in etltlhle, as ihtlic'ateclin Figure l. The extension 32 is closed at the 6013; as inclicateclat'83.

The numeral 34 marks What may he 'clen'omirratecl a pi e connection, since "it ,is assemblecl ih-an'y suitable way with atnbe 35 adapte'l to' carry a discharge nozzle (hot shown). The connection 34 has l'iverg'lhg branches 36 that are joined tecasings 37loca'tecl on opposite sides of the extension 32 of the rotary tubular member 21. At their ixm'er ends, the casihgsB'Z have flanges Tubular 'c'bnne'ctions '89 are threaded into the sides of the extension 32 of the rotary member 21. The connections 39 have lateral flanges 40 located outwardly of the flanges 38 on the casings 37. The casings 37 are mounted to swing on the connections 39, and packing rings 41 are located between the flanges 40 and38. Closures 42 are threaded or mounted otherwise in. the outer ends of the casings 37 and carry glands 43 into which are threaded operating members in the form of screws 44, the screws 44 being provided at their outer ends with hand wheels 45, and being equipped at their inner ends with valves 46 which seat against the connections 39.

Waterenters the body 1 by way of the arms 2 and the valves 5 act as checks, in the event that water is not supplied by one or two of the arms 2. The water flows from the interior of the body 1 into the rotary tubular'member 21, by way of the ports 31, and, passing upwardly into the part 32 of the member 21, moves laterally through the connections 39, into the chambers or casings 37, and from the casings 37, the water finds its way into the tube or nozzle 35, by way of the'br'anches 36 of the pipe connection 34.

The supply to the nozzle may be regulated by closing one or both of the valves 46. The nozzle 'and the connection 34 have a compound movement. I First, the part 34 can swing about an axis represented by the axis ofthe connections 39, and, secondly, the rotary member 21 may be turned about its own axis. The nozzle, therefore, has practically a universal movement.

'It is not necessary or desirable to specify the particular purpose for whichthe article is intended, since this specification is addressed to a person skilled in the art, but it may be stated that the device is well adapted to withstand the strong reaction produced by anozzlethrough which astream of water is passing under heavy pressure. Furthermore, the article is so made that the nozzle may be turned and swung practically in any direction.

What is. claimed is: I

1. In a device of I the class described, a hollow body having an inlet, a tubular member journaled in the body, a discharge connection provided with branches located on opposite sides of the tubular member, a combined means for establishing communication between the branches of the connection and the tubular member and for mounting the 'journaled in the body, a discharge connection provided with branches, casings assembled with the branches and located on opposite body of sufficient horizontal extent to afford a substantial footing and support, the body having an inlet, a transverse coupling disposed above the body, the longitudinal axis of the coupling being substantially horizontal, means for connecting the coupling at a point intermediate its ends with the body for rotation about a vertical axis which passes through the geometrical center of the body, a nozzle connection having ing branches, and means for joining the branches of the nozzle connection to the coudivergpling on opposite sides of the vertical axis of i the body for rotation with respect to the longitudinal axis of the coupling, the longitudinal axis of the coupling and the vertical axis of the body being located in the same vertical plane, and the nozzleconnection being movable in a plane which coincides with the vertical axis of the body. 7

4. In a nozzle stand, a portable hollow body of sufficient horizontal extent to aflord a substantial footing and support, the body having an inlet, a transverse coupling disposed above the body, the longitudinal axis of the coupling being substantially horizontal, the coupling being provided intermediate its ends with a tubular part journaled'on the body for rotation about a vertical axis which passes through the geometrical center of the body, means engaging the bottom of the body and a part of the coupling for holding the coupling assembled with the body, a nozzle connection having diverging branches, and means for joining the branches of the nozzle connection to the coupling on opposite sides of the vertical axis of the body for rotation with respect to the longitudinal axis of the coupling, the longitudinal axis of the-coupling and the vertical axis of the body being located in the same vertical plane, and the nozzle connection being movable in a plane which coincides with the vertical axis ofthe body.

5. In a nozzle stand a portable hollow body of suflicientlateral extent to afford a substantial footing and support, the bodyv having an inlet, a transverse couplin disposed externally of the body, the longitudinal axis of the coupling being substantially parallel to the body, means for connecting the coupling at a point intermediate its ends with the body for rotation about an axis at right angles to the longitudinal axis of the coupling and passing through the geometrical center of the body, a nozzle connection having diverging branches, and means for joining the branches of the nozzle connec-v tion to the coupling on opposite sides of the last-specified axis for rotation With respect to the longitudinal axis of the coupling, the

longitudinal axis of the coupling and said axis of the body being located in the same plane at right angles to the body and the nozzle connection being movable in a plane which coincides with said axis of the body.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.
